FRONTEND GUIDE FOR AI CODING AGENTS - PART 11 - LeaveManagement Service

This document is a part of a REST API guide for the workforceos project. It is designed for AI agents that will generate frontend code to consume the project’s backend.

This document provides extensive instruction for the usage of leaveManagement

Service Access

LeaveManagement service management is handled through service specific base urls.

LeaveManagement service may be deployed to the preview server, staging server, or production server. Therefore,it has 3 access URLs. The frontend application must support all deployment environments during development, and the user should be able to select the target API server on the login page (already handled in first part.).

For the leaveManagement service, the base URLs are:

Tenant URL Prefix and Header Forwarding

Tenant context is resolved by frontend routing strategy:

Then backend API calls must always claim target tenant with header:

headers["mbx-company-codename"] = tenantCodenameFromUrl;

URL prefix/subdomain is frontend-only tenant selection. Use header forwarding for all tenant-scoped calls to leaveManagement service.

Scope

LeaveManagement Service Description

Handles employee leave/absence requests, review/approval workflows, and automatic integration with shift assignments, ensuring company data isolation and leave history access for employees and managers/admins.

LeaveManagement service provides apis and business logic for following data objects in workforceos application. Each data object may be either a central domain of the application data structure or a related helper data object for a central concept. Note that data object concept is equal to table concept in the database, in the service database each data object is represented as a db table scheme and the object instances as table rows.

leaveRequest Data Object: Tracks employee leave/absence requests including period, type, status, reason, and approval state. Linked to a user and (optionally) department, with audit fields for request and approval. Company-tenant scoped.

API Structure

Object Structure of a Successful Response

When the service processes requests successfully, it wraps the requested resource(s) within a JSON envelope. This envelope includes the data and essential metadata such as configuration details and pagination information, providing context to the client.

HTTP Status Codes:

Success Response Format:

For successful operations, the response includes a "status": "OK" property, signaling that the request executed successfully. The structure of a successful response is outlined below:

{
  "status":"OK",
  "statusCode": 200,   
  "elapsedMs":126,
  "ssoTime":120,
  "source": "db",
  "cacheKey": "hexCode",
  "userId": "ID",
  "sessionId": "ID",
  "requestId": "ID",
  "dataName":"products",
  "method":"GET",
  "action":"list",
  "appVersion":"Version",
  "rowCount":3,
  "products":[{},{},{}],
  "paging": {
    "pageNumber":1, 
    "pageRowCount":25, 
    "totalRowCount":3,
    "pageCount":1
  },
  "filters": [],
  "uiPermissions": []
}

Additional Data

Each API may include additional data besides the main data object, depending on the business logic of the API. These will be provided in each API’s response signature.

Error Response

If a request encounters an issue—whether due to a logical fault or a technical problem—the service responds with a standardized JSON error structure. The HTTP status code indicates the nature of the error, using commonly recognized codes for clarity:

Each error response is structured to provide meaningful insight into the problem, assisting in efficient diagnosis and resolution.

{
  "result": "ERR",
  "status": 400,
  "message": "errMsg_organizationIdisNotAValidID",
  "errCode": 400,
  "date": "2024-03-19T12:13:54.124Z",
  "detail": "String"
}

LeaveRequest Data Object

Tracks employee leave/absence requests including period, type, status, reason, and approval state. Linked to a user and (optionally) department, with audit fields for request and approval. Company-tenant scoped.

LeaveRequest Data Object Frontend Description By The Backend Architect

LeaveRequest Data Object Properties

LeaveRequest data object has got following properties that are represented as table fields in the database scheme. These properties don’t stand just for data storage, but each may have different settings to manage the business logic.

Property Type IsArray Required Secret Description
userId ID false Yes No ID of employee/user requesting leave (auth:user.id)
departmentId ID false No No Department (userGroup) id, for scoping leave if relevant
requestDate Date false Yes No Datetime when leave requested
leaveType String false Yes No Type of leave (e.g. vacation, sick, emergency).
startDate Date false Yes No First day of leave (inclusive).
endDate Date false Yes No Last day of leave (inclusive).
reason String false No No Employee-provided reason/message for leave request
status Enum false Yes No Leave request status (pending, approved, rejected, cancelled).
approverId ID false No No UserId of manager/admin who approved/rejected/cancelled the request
approvedDate Date false No No Date/time leave was approved/rejected/cancelled, if applicable.
companyId ID false Yes No An ID value to represent the tenant id of the company

Enum Properties

Enum properties are defined with a set of allowed values, ensuring that only valid options can be assigned to them. The enum options value will be stored as strings in the database, but when a data object is created an additional property with the same name plus an idx suffix will be created, which will hold the index of the selected enum option. You can use the {fieldName_idx} property to sort by the enum value or when your enum options represent a hiyerarchy of values. In the frontend input components, enum type properties should only accept values from an option component that lists the enum options.

Relation Properties

userId departmentId approverId

Mindbricks supports relations between data objects, allowing you to define how objects are linked together. The relations may reference to a data object either in this service or in another service. Id the reference is remote, backend handles the relations through service communication or elastic search. These relations should be respected in the frontend so that instaead of showing the related objects id, the frontend should list human readable values from other data objects. If the relation points to another service, frontend should use the referenced service api in case it needs related data. The relation logic is montly handled in backend so the api responses feeds the frontend about the relational data. In mmost cases the api response will provide the relational data as well as the main one.

In frontend, please ensure that,

1- instaead of these relational ids you show the main human readable field of the related target data (like name), 2- if this data object needs a user input of these relational ids, you should provide a combobox with the list of possible records or (a searchbox) to select with the realted target data object main human readable field.

The target object is a sibling object, meaning that the relation is a many-to-one or one-to-one relationship from this object to the target.

Required: Yes

The target object is a sibling object, meaning that the relation is a many-to-one or one-to-one relationship from this object to the target.

Required: No

The target object is a sibling object, meaning that the relation is a many-to-one or one-to-one relationship from this object to the target.

Required: No

Filter Properties

userId departmentId leaveType startDate endDate status companyId

Filter properties are used to define parameters that can be used in query filters, allowing for dynamic data retrieval based on user input or predefined criteria. These properties are automatically mapped as API parameters in the listing API’s.

Default CRUD APIs

For each data object, the backend architect may designate default APIs for standard operations (create, update, delete, get, list). These are the APIs that frontend CRUD forms and AI agents should use for basic record management. If no default is explicitly set (isDefaultApi), the frontend generator auto-discovers the most general API for each operation.

LeaveRequest Default APIs

Operation API Name Route Explicitly Set
Create createLeaveRequest /v1/leaverequests Yes
Update updateLeaveRequest /v1/leaverequests/:leaveRequestId Yes
Delete deleteLeaveRequest /v1/leaverequests/:leaveRequestId Yes
Get getLeaveRequest /v1/leaverequests/:leaveRequestId Yes
List listLeaveRequests /v1/leaverequests Yes

When building CRUD forms for a data object, use the default create/update APIs listed above. The form fields should correspond to the API’s body parameters. For relation fields, render a dropdown loaded from the related object’s list API using the display label property.
